Sensitivity Analysis of In-pile Critical Heat Flux Experiments in TREAT. Part I: Characterization of RIA Power Transient Effects
A reactivity-initiated accident (RIA) is one type of postulated design basis accident (DBA) that can cause a departure from nucleate boiling (DNB) event in pressurized-water reactors (PWRs). A DNB occurrence and its consequences depend on the thermophysical properties of the fuel components and coolant, characteristics of the transient energy insertion into the fuel rod, and […]
